Acrylic Sump Thickness for Fluval Sea m40

[mameroo]

Hello everyone.

I have a fluval sea m40 all in one setup and I would like to add a sump in the cabinet that will fit 12" cube 

Sump perfectly. I was searching for a glass or acrylic tank in that size but without luck. 

However I found an acrylic Display box for a really good piece 

Its 12"x12"×12"  1/8" thick. I'll leave the link below 

My question, is 1/8" thick acrylic should be fine for a sump or should I keep searching for different one???

Some update on my sump. Finally I managed to build the sump out of 1/8" acrylic. I also made algae turf scrubber. 

Drilled my tank for the overflow and finished all plumbing.
